Developmental research has consistently shown that peers’ influence is a key factor in adolescent risk-taking, but parents also continue to play a decisive role in their teenager's risky behaviours. Indeed parental presence, monitoring and increase in parent-child positive relationship promote adolescents’ safe behaviours (Qu et al. 2017; Telzer et al., 2015). However, while overprotective parenting - defined as excessive parents’ level of protection and involvement considering the child’s development - is associated with less autonomy, more externalized behaviours, depressive and anxious symptoms (Van Petegem et al., 2020; 2021), the effect of overprotection on risk-taking remains underexplored. The present study 1) examine whether parental overprotection limits or promotes adolescent risk-taking, and 2) study the effect of overprotection on the relative influence of parents/peers in the case of contradictory injunctions concerning risky behaviours. A cross-sectional sample of 11 to 18 adolescents completed a risk-taking inventory, a multidimensional overprotective parenting scale (S-MOPS), a personality scale (BFI) and scenarios in which their parents promoted caution while their peers encouraged a risky behaviour. Preliminary results show that anxious overprotection increases adolescents' transgressive and social risk-taking behaviors. More specifically, non-linear models show that risk-taking increases with the level of overprotection, and this effect becomes more pronounced with age. Only an extreme level of overprotection seems to limit adolescent risk-taking. Finally, the negative effect of overprotection on risk-taking is mediated by greater adherence to peer influence and rejection of parental advice. Results will be discussed considering the opportunities for exploration and learning limited by parental overprotection.
